Description

The TC9457F is a firmware incorporating CD digital servo system. In addition to an LCD/LED driver, 4-channel 6-bit AD converters, and 2-wire/3-wire serial interface, it has a buzzerfunction, interrupt function, and 8-bit timer/counter. The TC9457F CPU allows selection of the operating clock from three types of crystaloscillators (16.9344 MHz, 4.5 MHz, and 75 kHz), making interfacing with a CD easy. The CD digital servo incorporatesvarious functions and circuits required for CD systems. These include sync separation protection and interpolation, EFM demodulation, error correction, digital equalizer for servoing, a servo control circuit. Furthermore, it contains a 1-bit DA converter, so that when combined with the digital servo head amp TA2109F, TC9457F allows you to create a maintenance-free, extremely simple CD player system.
